Medium Nessus Plugin ID 117558
SynopsisThe remote EulerOS Virtualization host is missing a security update.
DescriptionAccording to the version of the php packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerability :
- The GIF decoding function gdImageCreateFromGifCtx in gd_gif_in.c in the GD Graphics Library (aka libgd), as used in PHP before 5.6.31 and 7.x before 7.1.7, does not zero colorMap arrays before use. A specially crafted GIF image could use the uninitialized tables to read ~700 bytes from the top of the stack, potentially disclosing sensitive information.(CVE-2017-7890)
Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
SolutionUpdate the affected php package.
